Neutral highly branched metallomacromolecules: incorporation of a (2,2′:6′,2′′-terpyridine)ruthenium(II) complex without external counterions

Abstract

Neutral dendritic metallomacromolecules possessing four bis-terpyridine Ru^II linking sites with internal counter ions have been prepared and their electrochemical properties have been studied.
